<p><span class="user-mention" data-user-id="116122">@simulacrum</span> ok, so I went through the open regressions for 1.47:</p>
<ul>
<li><a href="https://github.com/rust-lang/rust/issues/75982">#75982</a>: error -&gt; ICE, not a big deal</li>
<li><a href="https://github.com/rust-lang/rust/issues/76466">#76466</a>: lld is broken on windows 32bit, which means no wasm there</li>
<li><a href="https://github.com/rust-lang/rust/issues/76480">#76480</a>: macro hygiene -- really not happy about this, but I think the compiler team already expressed their concerns on this</li>
<li><a href="https://github.com/rust-lang/rust/issues/76736">#76736</a>: internal rustc docs error, not sure why it's marked as regression at all</li>
<li><a href="https://github.com/rust-lang/rust/issues/76980">#76980</a>: ugh</li>

<p>Well think we should figure out a timeline of when to commit to a decision on the release. I wonder if it would be good to instead of delaying the release, committing to a patch release, and say “hey if you use C++ in proc macros wait for a patch in a couple of weeks”? I have no experience with C++ so I don’t know how common that is.</p>

<p>Okay, so my current thinking on this is that we'll put a note in the release blog post basically saying that "We are aware of cases where C++ code linked into proc macros regressed in this release" and point at the issue. I don't think it is known to affect enough people to warrant delaying the release. Hopefully that might also get some eyes on it and HN or whatever suggests a solution...</p>

<p>With some more discussion on the issue, I think we actually have a fix I am comfortable backporting to stable and removing this regression entirely - we can disable llvm thinlto without a significant performance hit (~3% wall times on larger crates) and get a statically linked LLVM, which seems to avoid the bug at least in my small reproduction.</p>

<p><span class="user-mention" data-user-id="121055">@Pietro Albini</span> I would appreciate it if you could prepare a new stable build tomorrow when you wake up, so we can get maximal testing on it, but I will do so tomorrow when I wake up if not.</p>
<p>I don't want to land this on master because in the immediate future it'll break the LLVM downloads from CI but I'm fairly confident we can get a fix on master relatively quickly.</p>
